Load html into Richtextbox

I would like to load an html file into a richtextbox and be able to view the html tags. Basically, I would like the richtextbox to do what notepad does when opening an html file. Right now, when I use LoadFile for an html document the Richtextbox doesn't show the tags properly.

Here is a way you can do it with a regular textbox control, a filesystem object and a textstream.

Hope this helps :D
